      Hi,

      The temperature reported in the dashboard is way lower of what it should be. When it was actively cooled the cpu temp was lower than ambient temperature, it is impossible. Please fix that or show me a workaround.

      AMD Athlon 5350 @2.1Ghz
      Asus AM1M-A
      Kingston 4GB 1R 1600EC11 @C10
      Kingston V300 60GB
      Intel Pro/1000 PT dual (wan+lan)
      OEM 90w psu
      80mm case fan
      100/20M vdsl2+ internet connection
      pfsense 2.3.3dev
      some package installed

        2.3.2 is doing this also. I recently built a new box with a 5350 and noticed it.

            What my cpu isn't really running at 11 degrees? ;D

            Did you really check your cables?

              The FreeBSD drivers report only what the hardware tells them, they are not aware of the adjustment factors for various motherboards that need to be applied to the raw values to get the real temperatures and that's why the numbers make no sense as absolute numbers.

                If you "know" the difference (offset)

                You can use the "shellcmd option" and adjust/tune the value

                I've done this way with my "C70M1" MB

                
                <shellcmd>sysctl -a dev.amdtemp.0.sensor_offset:-18</shellcmd>

                  To complement @kpa and @ptt replies. The info on the following links may reveal to be useful.

                    Go to    System>Advanced>Miscellaneous and check you have AMD selected under the Cryptographic & Thermal Hardware header on the Thermal Sensor drop down.
